ROCHESTER — A Strafford County deputy sheriff who was one of four law enforcement officers at the scene of a fatal shooting March 10 has returned to duty.

When asked by Foster's if there was any update to the case after nearly two weeks of investigation, Strafford County Sheriff David Dubois said he had completed an internal investigation of the shooting. As a result, he said, he returned his deputy to “working on the street.”

Dubois would not identify the deputy. He said that detail should be released by the attorney general's office as part of the investigation.

The deputy was with three state probation and parole officers when the shooting occurred. The four officers were attempting to serve Benjamin Shannon, 34, with an arrest warrant March 10 at around 3 p.m. at his mother's mobile home at 28 Periwinkle Drive in Saks Mobile Home Park on Route 125.

The probation and parole officers involved in the incident are employees of the N.H. Probation and Parole Office. They have a close professional ties with the county sheriff's department and work out of leased space at the county courthouse in Dover.

According to Assistant Attorney General Benjamin Agati, probation and parole officers are licensed law enforcement agents who are typically armed when they perform tasks such as serving arrest warrants.

In earlier reports from Shannon's family, the four officers entered the mobile home that day after the family let them in. They went down a hallway to a door and the shooting began.

Authorities have not yet released details about what prompted the shooting.

After the shooting Shannon was taken to Frisbie Memorial Hospital in Rochester and then med-flighted to Maine Medical center where he died later that night.

The Maine medical examiner's report released four days after the shooting states Shannon died after suffering three gunshot wounds that struck his arms and torso. The report also concluded the manner of death was homicide, meaning death was inflicted by another person. The N.H. Attorney General's Office is conducting a probe of the shooting because it involved use of deadly force by law enforcement officers.

The AG's office said no legal conclusion has been made on whether a crime occurred.

The AG's release said no Rochester police officers were involved in the shooting, though city officers did respond to the scene after shots were fired.

The warrant was issued because Shannon had been charged with violating bail conditions set in a robbery case, according to court documents.

Shannon had been out on bail after his arrest Feb. 17 on a felony charge alleging he robbed George and Ed's convenience store at gunpoint on North Main Street in Rochester that same day.

During his Feb. 18 arraignment, it was revealed Shannon had a problem with alcohol and that he was detoxing.

Authorities said Shannon violated bail conditions while being supervised by Strafford County Community Corrections (SCCC). Shannon, who had been ordered not to consume any alcohol, failed breath tests several times from March 1 to March 3.

On March 3, Shannon was asked to report to the SCCC office, but failed to do so, according to a motion requesting an arrest warrant.

Late last week Agati said additional interviews still need to be done, and that his office is also awaiting toxicology results, which typically take 30 to 45 days.
